.' b all whom it may concern:

Be it known that we, CHARLES E. WRY and CLAlR ,R. Jones, citizens of theUnited States, residing at Forest City, in the county of Winnebago andState of Iowa, have invented a new and useful Acetylene-Gas Generator,of which the following is a specisize as desired.

fication.

' The objects of our invention are, first, to provide a simple,inexpensive and eflioient self-feeding acetylene gas generator in whichthe carbid is stationary and the water elevated by air pressure toperiodically wet the carbid': second, to provide means for safelyrefilling the carbid tank while the machine is in operation: third, toautomatically elevate water into the carbid chamber as required forwetting the carbid and generating gas by means of air and pressure:fourth, to provide means forretain'ing the carbid chamber perpendicularrelative to a water chamber as required to maintain water circula tionand preventing leakage: Our invention consists in the economicarrangement and combination of two Water tanks, a detachable carbidholder and a gas receiver as hereinafter set forth, pointed out in purclaims and illustrated in the accompanying drawing in which the letter Adesignates a main water tank that may vary in It has a closed top, 10,provided with a central open neck 12, to which is fitted a removable cap13 to which ca is connected an air pump, 14, that is preferably fixed toside of the tank as shown. A flexible tube, 15, extends from thepump,14, to the cap 13. A second water tank B is connected. with thelower tank A by a tube 16 as required to allow continuous communicationbetween the two tanks.

With the closed top of the tank B is com nec'ted a removable air-tightcarbid holder C by a coupling 17 that is provided with a cutolfv'alve18. Above the coupling 17 is a cut off valve, 19. The valves 18and 19 are only for the purpose of shutting off the water pressure whenit is desired to refill the carbid chamber or in case of disconnectingthe machine at-some other point. At all other times these valves remainopen, leaving the water free to enter the carbid chamber whenever thegas pressure in the tank D is lower than the air pressure in the tankA;and also to allow water to drain out of the earbid chamber when-gaspressure in the tank D becomes stron enough to automatically force thewater back into the tank B.

To support the holder C in a perpendicular position a skeleton frame,composed of circular bands 20 and 21 and'a plurality of uprights 22fixed to the bands, is detachably band 23 fixed on the tank as shown, orin any suitable way, in such a manner that the upin concentric positiontherewith as shown in the drawing. The lower end of said holder isconcave-convex and has a flat bottomed central extension 24 providedwith a central screw-threaded opening into which the tube at the up )erend of the valve 19 is dot-a i. A screen 25 placed in the extension 24serves as a drainer.

The top of the holder C has a neck 26 to which is detachably fixed a cap27 and on the ca is a cut off valve 28. Another cut off valve 29 isdetaehably connected with the valve 28 bya union 30. tor pipe 31extendslfrom the valve 29 to a gas receiver D. By means of the union 30it is obvious the pipe can be readily detached from the holder C asrequired re liminary for disconnecting the said he der from the watertank B. A gas distributing pipe 32 is'fixed to the receiver D andprovided with a cut off valve 33. A pressure gage 34 on to of the gasreceiver indicates the pressure 0 the gas confined therein.

In the practical operation of our invention when all the parts are proor] y connected, water in the tanks A and and carbid in the holder G,air pumped into the tank A will force water up from the tank B throughthe open valves 18 and 19 as required to wet oarbid in the holder C forgenerating gas that -will pass up through the oarbid and through the 0en valves 28 and 29 into and through the pipe 31 into the receiver Dfrom whence it can 'he distributed to any number of burners that may beconnected with said distributing ipe. The quantity of water in the tanksX and B and the quantity of air pum ed into the tank A regulates the uwar pressure of the water in the tank and also the pressure of the gasin the holder C and the receiver D. And the air confined in the tank Awill press water into and up throu h the' tank B as re uired to wet thecarbitI in the holder C. e amount of air pumped on top of the water inthe tank A or band 21 will engage the carbid holder C fitted to thetopof the tank B to rest upon a I A gas eonducfunction and combinationof all'its parts the forces the Water into the carbid chamber andretains it there until sufiicient gas is generated to force the waterback out of the carbid chamber and compresses the air in the to of thetank A, as required to automatica ly drain the water from the carbidchamber and thus discontinue the eneration of gas. A stop cook 35 isprovi ed at the bottom of the tank A for emptying the water from thetanks. A very simple and complete means of regulating the generation ofgas and the quantity required is thus pro* vided by filling water intothe tank A and pumping air on its top. w

aving thus set forth the purpose of our invention, the construction,arrangement,

be obvious.

What we claim as new and desire to secure by Letters-Patent, is

1. In an acetylene gas generator, two Water tanks beside each other andcommunieating at their lower ends, ,an air pump con- 1 practicaloperation and utility thereof will 1 2. An acetylene gas generatorcomprising 7 two Water tanks communicating with eachother at their lowerends, an air pump connected with one of said tanks and a carbid holderon top of the other tank, a tube connecting the carbid holder with thetank under it, cut off valves in said tube, a gas receiver, a pipeconnecting said receiver with said holder, cut off valves in saidpipeand means for distributing gas from the receiver,

.arranged and combined to operate as set forth,
